CentOS 9.x CentOS 9 released

buik · Nov 3, 2021

As Red Hat Enterprise Linux 9 is around the corner.
CentOS 9 is released as part of the RHEL 9 development process.

As written before the CentOS project shifts focus to CentOS Stream.
In system administrator language, without all the CentOS marketing talk.
CentOS is now Red Hat Enterprise Linux (RHEL) Beta.
And a CentOS 9 (unrelated to version 7) user is now a free BETA tester.

If you are looking for a stable server operating system for your server.
Based on RHEL and like the former CentOS: A RHEL rebuild.
Then consider: Oracle Linux, Rocky Linux, Almalinux, Navy Linux or Virtuozzo VzLinux.

P.s. CentOS (>7) support will effectively end in a month.
I suspect that CentOS Stream will be renamed to CentOS at that time.
As BETA testing is is their new king of the castle.

Huh GCC 11 is still BETA for EL7 in Red Hat Developer Toolset 11.
Are you selfcompiling GCC 11?

Using their pre-release RPMs - ones prior to being pushed to YUM repo for SCL. Just to test and make sure when official GCC 11 devtoolset-11 is pushed to YUM repo for SCL, that Centmin Mod Nginx and PHP compile properly for GCC 11

Because CentOS now recommends Stream 9 as the first download by default.
And CentOS disappears within a few days.
I have tested CentOS Stream 9 again.

As CentOS Stream is described by Red Hat it is:

To the untrained eye, CentOS Stream is
already as stable as RHEL.

This is what I get from the very first task after booting for the first time with this up-to-date test system on a dedi server. In addition, the user has sufficient rights.

In short, my advice. Absolutly don't run CentOS Stream in production. Do not be led to believe by Red Hat that CentOS Stream is as stable as Red Hat Enterprise Linux (RHEL). CentOS Stream feels and runs like a BETA/Alpha. Wrapped up in a tasty pastry called marketing.

P.s. the server is installed via IPMI therefore the small screen.

Yeah does seem like Redhat just want a lot of free beta testers to use CentOS Stream for el8/el9 to make their Redhat Enterprise Linux better. CentOS use to be a name associated with a stable unchanging OS that folks could rely on to build their servers off of i.e. CentOS 7. But now CentOS 8/9 isn't the same thing.
